Looking at the mkIV GTi turbo upgrades and one question comes to mind, how can 240+ through the front wheels grip? gears restricted? AWD upgrade? i may have missed something but can someone enlighten me

240bhp through the front wheels is quite an acceptable amount of power for the car to put down. It is when you want to increase this power past the 300bhp mark that a differential would be usefull. We have had some very decent results with Waivetrac Diffs and continue to use them on our development cars. A decent set of grippy tyres always helps too!
